SAMPLE EXAM MATH 200 Calculus 1 (Bueler) Final Exam: Comprehensive Part 100 points total for this part. You have 120 minutes for both parts together. 1. (b) 2. (b) (a) (5 pts) Compute f 0 (5) if f (x) = x−2 . (5 pts) Use the definition of the derivative to compute f 0 (5) if f (x) = x−2 . (a) (5 pts) Find dy/dx if √ y = 2 x + 6ex (5 pts) Compute Z √ 2 x + 6ex dx 3. (10 pts) The equation x2 − xy + y 2 = 4 is an ellipse. (2, 0) is a point on this ellipse. Find the equation of the tangent line to this ellipse at this point. (Hint: There is no need to sketch any graph.) 4. Consider the curve y= 4−x . x−1 (a) (5 pts) Is this curve even, odd, or neither? (b) (5 pts) Find the intercepts (locations where the graph crosses the x and the y axes). (c) (5 pts) Find the intervals on which the curve is increasing and decreasing. (d) (5 pts) Sketch the graph, showing any asymptotes. 5. (10 pts) Find the absolute maximum and minimum of f (t) = 2t − tan t on the interval [0, π/4]. 2 Final Exam: Comprehensive Part CONTINUED SAMPLE EXAM 6. (a) (5 pts) Bismuth-210 is a radioactive substance whose mass decays exponentially. It has a half-life of 5.0 days. A sample originally has a mass of 800 mg. Find a formula for the mass y(t) remaining after t days. (b) (5 pts) Find the mass remaining after 15 days. 7. (10 pts) Define “ lim f (x) = L ” x→a You may use either the sentence definition written many times in lecture, or you may use the –δ definition. 8. (10 pts) Compute Z 7 cos x 4 dx 3 sin x 9. (10 pts) Find the area between y = ex and y = 1/x on the interval [1, 2]. Extra Credit. (3 pts) Show that d 1 (arcsec x) = √ dx x x2 − 1 You may use known derivatives of trignometric functions, but not, naturally, the derivatives of inverse trigonometric functions. You may use standard trigonometric identities.
